Microprocessor-based data collection systems are being actively implemented in all spheres of human activity. No exception is energy accounting system. The paper provides an overview of the development of the computer system automatically records the used hot water supplied by the energy of the measured signal. In this paper we developed a combined system of data collection that contains the mechanical-electrical and ultrasonic component. For data storage, specialized non-volatile memory chip, which for data transmission via radio. Also, this circuit can be powered by the energy of the signal reader that allows you to receive data even after system failure. Such an approach will ensure energy independence the accounting system and improve the quality assessment of energy consumption. This paper analyzes the existing technologies and their possible applications in energy metering devices powered by the energy of the measured signal.
